 End wireless connections such as Bluetooth, 802.11b/g or GSM/GPRS which are not in
use.
 Shorten the Backlight turn off time, go to Start Screen | Settings | System, and
tap Screen Backlight. Refer to

.
 Disable key light function, go to Start Screen | Settings | System, and tap Keypad
Backlight to select Always Off to disable keypad Backlight function.
 Go to Start Screen | Settings, and tap Power.
In the Battery tab, you may monitor the charging status.
